Set on 5.16 private acres atop a wooded hilltop in the borough of Sewickley Heights, 950 Blackburn Road is a 3,790-square-foot contemporary retreat that has spent more than four decades quietly conversing with its landscape. Built in 1980 and shaped by the modernist conviction that a house should rise from its site rather than perch upon it, the residence balances soaring architectural geometry with the warmth of natural materials — most memorably, the hand-laid river-stone masonry that anchors both the great room and the open-air terrace beyond. Investments include a new roof, fully renovated kitchen and baths, and fresh paint throughout, allowing the next owners to move in and simply enjoy.Approach is a study in restraint. A long ribbon of lawn unfurls beneath a canopy of oaks and maples, and the home reveals itself in dark cedar planes and pitched gables, quietly confident. Inside, herringbone terracotta floors lead past a sculpted floating staircase into a light-flooded living room where coffered ceilings and walls of glass gather around a baby grand. Two wood-burning fireplaces — one anchoring the soaring two-story family room, one warming the living room — bring the warmth of the season indoors, while outside, a built-in stone charcoal grill station and wide-plank deck set the stage for summer entertaining around the sparkling in-ground pool.The pool is a true outdoor centerpiece. Surrounded by mature trees and enveloped in complete privacy, it's perfect for summer entertaining or quiet afternoon swims with nothing but birdsong and treetops above — a rare combination of resort-quality amenity and untouched natural setting that the five-acre lot makes possible.The heart of the home is a soaring double-story family room where a hand-laid river-stone fireplace climbs to the ceiling, a handcrafted spiral staircase rises to a book-lined loft above, and walls of glass open directly onto a pergola-covered deck with the pool glimmering below. The kitchen flows seamlessly from this space — navy cabinetry, honed white quartz, Sub-Zero refrigerator, Miele dishwasher, and double ovens — designed for the way people actually live, with the loft, the living room, and the outdoors all within reach.A glass-roofed solarium opens to the gardens — made for morning coffee, candlelit suppers, orchids in winter. The formal dining room, framed in soft sage and crystal, was built for long tables and longer stories.Three bedrooms and three-and-a-half baths are arranged for privacy and quiet. The primary suite is the architect's crescendo: a cathedral-ceilinged sanctuary with exposed white trusses, a private balcony into the treetops, and a spa bath skylit beneath the eaves with soaking tub, dual vanities, and forest views from every angle.A three-car garage, generous storage throughout, and a lower level dedicated to utility and organization keep the architecture uncluttered and the living spaces serene. The lot rolls in mature lawn and woodland — utterly private, yet minutes from Sewickley Village with easy access to major highways, about a 20-minute drive to downtown Pittsburgh and Pittsburgh International Airport. A lovingly maintained estate in one of Western Pennsylvania's most coveted enclaves.
